Analysis of manufacturing of component by elastoforming technology
Lorenc, Tomáš ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
In this thesis, processed within the master's degree is the analysis and proposals for modification of production stagnation ribs aircraft L-410. The part is made of aluminum alloy D16. More specifically, it is a 0.8 mm thickness sheet, which after the milling of the blank molded in the basic non-rigid tool by Guerin. After analyzing the entire manufacturing process and the determination of the critical points due to a series of tests carried out were evaluated possible variants production innovation. Proposed changes and their optimization can reduce the labor intensity deleting some time being necessary preparatory and finishing operations manual. It also increases the repeatability and streamline current production panels.

Sheet Metal Stretch Forming Process
Lorenc, Tomáš ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
In this work, elaborated in the bachelor study, there is a general overview of the sheet metal stretch forming methods. The stretch forming processes shift the boundary properties of the materials and merge process of drawing and bending into one operation. That's why it's possible to do products from materials, which can not be possible to form by other methods in the same quality Positives of this technology are the minimization of cushioning, the production of complex, precise surface shapes, etc. The contribution of this work is a systematic summary of the principles that should be used as a tool for teaching or as a basis for the wider development of this method.

Manufacturing of part of garage automatic door lock by compound tool
Vaverka, Ivo ; Šlais, Miroslav (referee) ; Peterková, Eva (advisor)
This master’s thesis created in the master studies of the M-STG Manufacturing technology is focused on the manufacturing of a part of a garage automatic door lock by a compound tool. The part is made of a rolled steel coil of the S275JR material with the thickness of 2 mm. The number of parts manufactured per year equals to 600 000. Literary studies deals with the issues of cutting and bending. On the basis of the most advantageous manufacturing variant and technological calculations the compound tool is designed. As a working machine the eccentric press LEK 160 is chosen. In the economical evaluation part, the calculations to finding out when the manufactory becomes profitable are carried out.

Bending technology profile of steel
Kameník, Tomáš ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
KAMENÍK Tomáš: Bending technology profile of steel The project has been elaborated within the master's of studies of the subject M-STG manufacturing technology and it presents the lay-out of the bending technology profile of steel from the material S235JRG2. The bend is made by the bending and the press tools. The press tools and the bending profile were suggested on the bases of the literature study of technology bending. In consideration of the calculated bending power and the dimension profile will be made profile on the hydraulic press CYS 320 ( the manufacturer ŠMERAL Brno a.s.). At the end of the the thesis there are performed calculations of the technical and economic evaluation for the machine press and the bending .

Issues of drop forging on presses
Jelínek, Tomáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This thesis is focused on the issue of drop forging on presses. The power forming machines works with calm pressure of the forging part. Their main disadvantage is the forging of the slag layer into the product. Hydraulic and mechanical presses are used for drop forging. This technology is mainly used in series production in most industries. To achieve a quality forging is necessary proper heating of the semi-finished product to the forging temperature. This reduces deformation resistance, tool wear and the required forming force The design of the forging is based on the drawing documentation of the required part. The shape of the product is driving for the dividing plane, the size of the stock, the permissible geometry deviations and tolerances. It is also necessary to take into account the flash groove, the clamping of the dies and the type of ejector. There are many companies in the market that deal with die forging. For clarity, several of them are listed, with an overview of the machine and production portfolio.

The Machines and Tools for the Fineblanking Technology
Šindelka, Marek ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This work provides a brief overview of the used machines and tools designed for fineblanking. Fineblanking is a technology from the field of the surface forming, suitable especially for mass production, which can be used to make a functional component in a single operation. This work also lists the various methods of precision cutting, and describes the tools, that are the main reason for the quality of the product. Furthermore, in this work are listed some examples from today in practice used machines and their planting into the entire complex of production lines.

Production of forging piece "Spanner"
Vávra, Jan ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
Projects developed within the bachelor's degree in Mechanical Engineering, presented a proposal technology forged wrench - the hot-rolled steel bars 11 523.0. The thesis also compares the past with conventional methods of production and considering the new technological process of manufacturing. Based on the literature studies about fitting and calculations, was chosen to die forging hammer KHZ 2 A (producer ŠMERAL Brno, plant Hronov), with nominal energy of 20 kJ working pressure of 16 MPa and 30 kW electric power.
